PROVIDENCE, R.I. (AP) — Rhode Island House Speaker Gordon Fox says he is resigning from his leadership post and will not run for re-election, a day after federal and state law authorities raided his Statehouse office and home.

Majority Leader Nicholas Mattiello called an “informational caucus” Friday evening to talk about “the future of the House.” He says he has enough votes to be speaker.

Authorities raided Fox’s Statehouse office and home Friday as part of an investigation by the U.S. attorney’s office, FBI, IRS and state police. Officials haven’t said whom or what they are investigating.

A U.S. attorney’s office spokesman, Jim Martin, wouldn’t comment when asked whether the House speaker was being investigated. He said two federal search warrants had been executed, but he wouldn’t say whether they were connected to Fox.

Fox is just the latest politician to be wrapped up in a criminal investigation in Rhode Island, a state with a long history of elected officials getting into trouble with the law. Former Independent Providence Mayor Buddy Cianci, one of the longest-serving mayors in U.S. history, went to prison in 2002 for racketeering conspiracy after a federal probe found he presided over widespread corruption in office. Former Republican Gov. Edward DiPrete went to prison in the 1990s after admitting he took bribes while in office.

Fox has represented Providence for more than two decades in the state’s part-time General Assembly, and he became the nation’s first openly gay House speaker in 2010. He has a private law practice.
